BootP server: a server can be set up to automatically configure meter network
settings. See “Configuring Meter Network Settings” on page 274.
Firewall: to access the meter from beyond the corporate network, a firewall
configured for your meter is recommended. For WebMeter equipped devices,
HTTP uses TCP/IP port 80; you must configure the firewall to allow incoming
connections on TCP/IP port 80 to read the meter.
